Benefits of technology

This patent describes an electronic impression tray that can be used in dentistry to collect three-dimensional and temporal information. The tray has optical sensors distributed over it to capture the shape of the dental arch with a single or multiple impressions. The tray can change its shape by deformation or be designed with multiple elements that are hinged to one another. The invention aims to provide a comfortable and speedy experience for the patient while requiring minimal training for the practitioner and keeping reasonable investment.

Problems solved by technology

It turns out that the knowledge of bone contours, associated with the optical impression, requires complex manipulations and significant knowledge, which has led to the need to design a global impression system to respond to specifications.

Embodiment Construction

[0061]The present invention consists of an impression tray comprising cameras and light projection means, intended to be arranged facing a dental arch or part of an arch.

[0062]With reference to FIGS. 1a, 1b, 1c and 1d, different types of electronic impression tray 1 according to the invention can be seen, which comprise a part 2 equipped with series of optical measurement sensors C, arranged according to the intended use of the impression tray, whereby the different types of impression tray 1 shown in these figures each allow the impression of a defined part of a dental arch to be obtained.

[0063]The part 2 essentially has two parts, one part 20 constituting a handle for gripping by the practitioner, and one active part 21, which comprises the sensors C.

[0064]Thus, FIGS. 1a and 1b show impression trays 1 intended for the impression of a semi-arch, and FIGS. 1c and 1d of impression trays 1 for obtaining the impression of part of an arch.

[0065]It will be noted that the part preferably ...

Abstract

An electronic impression tray can be used to obtain three-dimensional and temporal measurements in dentistry. There is a device having optical measurement sensor system, and an electronic system including a central management unit capable of collecting, storing and ordering the data obtained by the sensor systems distributed over all or part of the impression tray. An optical impression of all or part of a dental arch can be obtained with a single or multiple impressions. The tray includes a part having the shape of all or part of a dental arch, and the part can change by virtue of its ability to deform and / or a structure formed by multiple elements that are hinged to one another and / or reversibly assembled and secured to one another, such as to provide the optimal shape.
